Unable to see logs when running pytest

[astrochun]

I have a basic logging configuration as follow:

import logging

from rich.logging import RichHandler

FORMAT = "%(message)s"

logging.basicConfig(
    level=logging.INFO,
    format=FORMAT,
    datefmt="[%X]",
    handlers=[RichHandler(markup=True, show_path=False)],
)

app_log = logging.getLogger("rich")

I've configured pytest and coverage as follow in my pyproject.toml:

[tool.pytest.ini_options]
addopts = "-sv --asyncio-mode=strict"
testpaths = [
    "tests",
]

[tool.coverage.paths]
source = ["src"]

[tool.coverage.run]
branch = true
command_line = "-m pytest"
source = ["src"]

[tool.coverage.report]
show_missing = true
precision = 2
skip_empty = true

When I run a basic unit test of multiple app_log.*() calls, I get the following:

tests/test_config.py::test_config test
PASSED
tests/test_logger.py::test_logger PASSED

I would have expected to see the log calls but it seems that with a basicConfig it doesn't work. It works via dictConfig in another project. I was hoping to use basicConfig for simplicity.

Actually, I think I came up with a fix. See: https://docs.pytest.org/en/7.1.x/reference/reference.html#confval-log_cli

What I don't understand is why this works; however, in another repo where is use logging.dictConfig it still prints the log even without setting this as true.

Honestly, don't know. The RichHandler just writes to stdout. I wouldn't be surprised if pytest does some magic to capture logs, but isn't aware of the RichHandler.
